objective oxygen intoxication plays an important role in the pathogenesis of some fetal diseases such as encephalopathy, ischemia& hypoxia. antioxidants can reduce oxidative damage in newborns. the object of this research was measuring total value of antioxidant and vitamin c in blood sample of pregnant women before delivery, and also in umbilical cord blood of their newborn, and repeating thes...
background: brain hypoxia-ischemia is a human neonatal injury that is considered a candidate for stem cell therapy. methods: the possible therapeutic potential of human umbilical cord blood (hucb) stem cells was evaluated in 14-day-old rats subjected to the right common carotid occlusion, a model of neonatal brain hypoxia-ischemia. seven days after hypoxia-ischemia, rats received either saline ...
background: considering the increasing rates of early hospital discharge and kernicterus in healthy full term newborns, timely identification of neonates at risk of severe hyperbilirubinemia is of great significance. the aim of this study was to investigate the predictive value of umbilical cord serum (ucs) bilirubin level for subsequent hyperbilirubinemia. moreover, we compared the predictive ...
Background and Objective: Nowadays, although umbilical cord blood is a commonly used source of hematopoietic stem cell, its low frequency of these cells is the main factor limiting its clinical application. The transplantation of hematopoietic stem cells derived from placenta tissue along with umbilical cord blood cells of the same sample may be an appropriate approach to solve this problem. In...
Introduction: The aim of study was to compare umbilical cord blood selenium levels in respiratory distress syndrome (RDS) and non RDS preterm babies. Methods: Umbilical cord blood selenium levels of all preterm newborn born during a 6-month period were enrolled in the study. They were divided into two groups: RDS and non RDS. Selenium level was assessed by using electro-thermal atomic ab...
ess the relationship between umbilical cord blood gases at birth and morphology of umbilical cord, in a prospective study of 200 consecutive term delivery, we investigated the relationship between umbilical cord morphology characteristics (umbilical crd length, number of vascular coil, coiling index) and color of amniotic fluid and umbilical vessel blood gases. statistically significant linear ...
background: umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell transplantation (hsct), used in leukemia treatment. cd26+ cells, a fraction of cd34 positive cells, are a major population of ucb cells which negatively regulate the in vivo homing and engraftment of hscs. cd26 is highly expressed in various cells such as hscs, immune cells, fibroblasts, and epithelial ce...
objective: to compare the maternal and umbilical cord serum selenium concentrations in low and normal birth weight neonates. materials and methods: a case-control study was carried out in vali-asr and akbarabadi hospitals (jan. to dec. 2013). two groups; case group; 91 mothers who delivered a low birth weight (lbw) neonate and control group; 86 subjects who delivered a normal birth weight neona...
Background: Previous studies have suggested the presence of a relationship between the increase of NRBC and the duration and intensity of asphyxia. The purpose of this study was to evaluate the relationship of fetal heart rate pattern and the number of NRBC's in umbilical cord blood sample at birth. Methods: We enrolled 322 pregnant women with healthy, term fetuses who referred to Mirza Koucha...
